“Physiologists should think before putting down the instinct of self-preservation as the cardinal instinct of an organic being. A living thing seeks above all to discharge its strength--life itself is will to power; self-preservation is only one of the indirect and most frequent results.” (BGE 13).
"Life itself is...the instinct for growth,... for power: where the will to power is lacking there is decline. It is my contention that all the suprememvalues of mankind lack this will"(Antichrist 6)
